Did you know you can have a migraine without a headache? Migraines have different stages, and some people just don't go through the "ache" stage. I think I may have had a migraine a couple of nights ago. I was at a school function and the lights began to feel really bright. A headache began over my eyebrows, but it slowly went away. Over the next couple of hours though, I began to feel worse and worse. I was dizzy, kinda of naseous, and my head just felt weird. I felt spacy. I could feel the loud noises pounding in my head...not a painful pounding but a resonating pound - I could feel noise. As I was going home, I could feel the oncoming headlights doing the same thing to my head, like I could feel the lights passing by. When I got home, I laid down in the pitch black and silence until most of it went away. The dizziness did not fully go away until I woke up the next morning.
I've had the same problem numerous times before, but I had never thought that it could possibly fall under migraines. I do know it usually occurs when I've been straining my eyes too much or ignoring the image out of one eye. It most often occurs at movie theaters. I don't like going to see action movies on the big screen anymore because they mess with my head. It's like I can't handle so much loud noise and movement all at once.
